For example, looking for two presets, using DI3 for one speed and DI4 for the second speed.
Assign 2 Preset Speeds to DI3
Assign 4 Preset Speeds to DI4
Set Preset Speed 2 for the first frequency desired
Set Preset Speed 3 for the second frequency.

How it works:
Close the run command and DI3, the drive will run at Preset Speed 2
Close the run command and DI4, the drive will run at Preset Speed 3
If both DI3 and DI4 are closed at the same time, the drive would operate at Preset Speed 4.
